Disclamer: I am not very computer savvy at all. And the problem I have is caused by my almost complete ignorance of anything computer/technical. I am hoping/praying someone on the forum can help me out.

Before I knew anything at all about DNA files, I had my brother do a YDNA test through ancestry.com. When I got the results, I downloaded it. It downloaded into a zip file. I didn't know any better, and I tried to "open" it to see what it said. It gave me the choice to open in Excel, so I did. It gave me two choices in Excel, so I saved it in comma delimited.....

Now I want to upload that YDNA to gedmatch but they want the original unopened zip file. Is there any way to zip it back?

Needless to say, it is not recoverable from ancestry.com as they have discontinued any support for the Ydna tests they sold.

Thanks in advance for any help.
